Nano is a crypto that defines itself as “a low-latency payment platform that requires minimal resources.”Nano's fundamental goal, like that of most cryptocurrencies, is to be a viable alternative to fiat money. It allows people around the world to use Nano Blockchain to carry out financial transactions and acquire goods and services. But, unlike other cryptocurrencies, Nano tries to achieve this goal in an eco-friendly way, not contributing to the emission of polluting gases into the environment. In addition, it aims to maintain a point where no fee is charged for conducting operations within the blockchain. To avoid collaborating in the pollution of the environment, Nano has devised a system so there is no need for mining in the emission of the cryptocurrency. For which, it launched its own emission system through captchas. Thus, anyone who wanted to acquire Nanos (Raiblock at the time) since 2015 only had to enter the foundation faucet and solve various complex captchas from which he would obtain a certain amount of Nano. This allowed to democratize the use of this blockchain since expensive hardware is not necessary to perform captchas and obtain the currency. In addition to this, Nano has created a platform that allows its users to carry out financial transactions, paying absolutely no commission. It makes an abysmal difference when compared to the high commissions charged by international financial institutions and other cryptocurrencies. Nano is one of the few cryptocurrencies in the world that care for the ecological well-being of our planet. And from this point of view, it is an undoubtedly unique case among virtual currencies, allowing to differentiate itself in such a crowded market. It has a noble goal and can attract the media’s attention since ecological initiatives have been on the rise recently.
